SPECIFICATION forming part of Letters Patent No. 412,435, dated October8, 1889.

Application filed April 26, 1889.` Serial No. 308,688. (No model.)

To a/ZZ whom it may concern:

Be it known that I, WILLIAM TURNER, a citizen of the "United States,residing at Moscow, in the county of 'Nez Perces and Territory of Idaho,have invented a new and useful Pump, of which the following isaspecication.

This invention relates to that class of pumps in which the water iselevated by pneumatic pressure upon the surface of the b ody of water;and it h a's for its object to provide a pump of this class which shallbe simple in construction and conveniently arranged for operation.

With these ends in view the invention consists in the improvedconstruction and arrangement of parts which will be hereinafterdescribed, and particularly pointed out in the claim.

In the drawings, Figure 1 is a vertical sectional view of a well havingmy improved pump applied thereto in position for operation. Fig. 2 is ahorizontal sectional view taken on the line w w in Fig. l. Fig. 3 is avertical sectional view, on a larger scale, of the pump-cylinder.

The same letters refer to the same parts in all the iigures. Y v

A designates the well, the walls of which are bricked up in such amanner as to render them air-tight and the top of which is provided witha cap or cover B, which is so constructed as to render the wellvperfectly airtight.

C is the pump-cylinder, which is mounted vertically in the top or coverB, and which is provided at its lower end with downward-extendingbrackets D D, connected by a crosspiece E. At the lower end of thecylinder is fitted an annular elastic packing-ring F,which bears againstan elastic cushion G, resting upon thev bracket E. 1

H is a piston which slides vertically in the cylinder C, and which isprovided with a downwardly-opening valve I. rIhe piston-rod .I extendsupwardly through the cylinder, and is connected at its upper end to alever K, which is fulcrumed to the upper end of the pitman L, the lowerend of which maybe connected to a bracket M, extending laterally fromthe upper end of the cylinder; or the pitman L may be pivoted to anyconvenient support.

N designates a vertical pipe extending through the cap or cover B andlreaching nearly to the bottom of the well. The upper end of the pipe Nhas a goose-neck O, and it is provided with a stop-cock P, by means ofwhich the flow of water may be regulated.

The operation of the device is as follows: By operating the piston H bymeans of the lever K 4air will be forced into the well above thewater'between the annular packing-ring F and the elastic cushion G,which will admit of air being forced int-o the well,while the expansionof the elastic cushion G against the packing-ring F will prevent the airescaping. The operation is continued until the air has been coInpressedto the greatest possible extent in the space labove thewater-line in the well. Whe'n the stop-cock P is opened,

the pressure of the air upon the surface of the body of water will causethe latter to flow through the pipe N as long as any air-pressure existsin the well.

I do not wish to be understood as limiting myself to theherein-described lever mechanism for operating the pump-piston, as anyother suitable mechanism may be used wit-hout departing from the spiritof ,my invention. Other details may also be altered,when

desirable, in the construction of the device. l

Having thus described my invention, I claim- Y The combination of thepump-cylinder terminating above the water-level and havingdownwardly-extending bracket-s connected by a cross-piece, an elasticcushion mounted upon the said cross-piece and bearing against an annularelastic packing-ring at the lower end of the cylinder,4 and thevertically-moving piston fitting in the cylinder and having adownwardlybpen ing valve, substantially as herein described, and for thepurpose specilied.-

In testimony that I claim the foregoing as Iny own I have hereto afXedmy signature in presence of two witnesses.

WILLIAM TURNER.
